Your bee needs to be absolutely positioned, something like this:
<div id="b" style="position:absolute; top:50px">B</div>
I've used a div here, but it could just as well be an <img>
tag. As meo pointed out, don't forget the top
attribute, because some browsers don't work without it. Then you can animate it:
$(document).ready(function() {
$("#b").animate({left: "+=500"}, 2000);
$("#b").animate({left: "-=300"}, 1000);
});
Here is a jsfiddle demo.
If you want to have a continuous animation as Hira pointed out, put the animation code in functions, make sure the left and right movement is the same, and use the onComplete option of animate() to call the next animation:
function beeLeft() {
$("#b").animate({left: "-=500"}, 2000, "swing", beeRight);
}
function beeRight() {
$("#b").animate({left: "+=500"}, 2000, "swing", beeLeft);
}
beeRight();
And the fiddle for that.
